FUNCTIONAL DESCRIPTION
All data given in this chapter are typical values, except
when otherwise specified.
Supply (pins LN, SLPE, VCC and REG)
The supply for the TEA1110A and its peripherals is
obtained from the telephone line. See Fig.3.
The IC generates a stabilized reference voltage (Vref)
between pins LN and SLPE. Vref is temperature
compensated and can be adjusted by means of an
external resistor (RVA). Vref equals 3.35 V and can be
increased by connecting RVA between pins REG
and SLPE (see Fig.4), or decreased by connecting RVA
between pins REG and LN. The voltage at pin REG is
used by the internal regulator to generate Vref and is
decoupled by CREG, which is connected to VEE. This
capacitor, converted into an equivalent inductance
(see Section “Set impedance”), realizes the set
impedance conversion from its DC value (RSLPE) to its AC
value (RCC in the audio-frequency range). The voltage at
pin SLPE is proportional to the line current.
The voltage at pin LN is:
Where:
Iline = line current
ICC = current consumption of the IC
IP = supply current for peripheral circuits
I* = current consumed between LN and VEE.
The preferred value for RSLPE is 20 Ω. Changing RSLPE will
affect more than the DC characteristics; it also influences
the microphone and DTMF gains, the gain control
characteristics, the sidetone level and the maximum
output swing on the line.
